– In this paper we investigate the impact of traffic patterns on wireless data networks. Modeling and simulation of the Cellular Digital Packet Data (CDPD) network of Telus Mobility (a commercial service provider) were performed using the OPNET tool. We use trace-driven simulations with genuine traffic trace collected from the CDPD network to evaluate the(More)
Recent research activities in the area of network traffic have demonstrated that traffic patterns in modern networks are statistically different from patterns generated by traditional traffic models. These new traffic patterns are long-range dependent. Researchers have shown that long-range dependency has considerable impacts on queueing performance, and(More)
This paper describes a new version of the DEN-ng context model, and how this model in conjunction with the DEN-ng policy model can be used for more effective and flexible context management. Both are part of the FOCALE autonomic network architecture. Context selects policies, which select roles that can be used, which in turn define allowed functionality(More)
Eclipse is an open source software project dedicated to providing a robust, full-featured, and commercial-quality platform for developing and supporting highly integrated software engineering tools. Excepting the small Eclipse runtime kernel, all the platform components are plug-in tools integrated seamlessly through predefined extension points. The(More)
Software reuse detection is a challenging task due to various modifications and the large size of software code. Most existing approaches adopt a token-based software representation and use sequential analysis for software reuse detection. Due to the intrinsic limitations of such a space-domain analysis, these methods have difficulties to handle statement(More)
Complexity has been one of the key challenges to the architecture, design, and implementation of large-scale and distributed enterprise applications. Object-oriented design overcame many of the scalability issues of previous technologies by applying encapsulation and inheritance. As systems became larger and more complex, classes and objects turned out to(More)
This paper describes a new version of the DEN-ng context model, and how this model in conjunction with the DEN-ng policy model can be used for more effective and flexible context management for autonomic networking. Both are part of the FOCALE autonomic network architecture. Context selects policies, which select roles that can be used, which in turn define(More)
